In vehicles running with high speed, especially in motor cars, theviolent current of air, which arises in driving, is very annoying forthe passengers of the car. If the air is saturated with soot and dust,this molestation will become even dangerous.

Apart from maladies of the respiratory organs caused by the draught, thenumerous particles of soot or dust will easily hurt the 1 eyes.

- In coaches, sedans and other closed bodies the current of air which,entering through the open windows, flows back from the back of the car,the socalled neckwind, isvery annoying and often the cause of very acuteand chronic neuralgias. r

The invention redresses these grievances by a wind-conductor which issultably designed to arrest and deflect the current of air into thefront part of the vehicle.

' A construction embodying the features of the invention is shown in theaccompanying drawings, wherein Figure 1 is a rear view of thewind-screen for a closed vehicle body, the body being shown in sectionon the line 11 of Fig.2.

Fig. 2 is a plan view of the device, the vehicle bod being shown insection on the line 2-2 of l ig. 1.

' Fig. 3 is a section (in the line 3-3 of Fig.- 1

showing the flow of air in the direction of the arrows.

Fig. 4 is a plan view illustrating a modification.

The wind-screen comprises a lower part or section 1 which is hinged, asat 3, to a strip 2 that is secured by screws to the door D of thevehicle body,-at the rear edge of the opening, and said section 1 may beswung toward gers when entering and leaving the vehicle.

The screen or guardhas an upper part or section 4 having its lower endoverlapping the upper end of the section 1. As seen in Fig. 4, thesection 4 may be rigidly secured to the wall of the vehicle bod yproviding said section with a flange 7a astened to said wall. It ispreferable, however, as seenin Figs. 1 and 2, to connect the section 4by a 6 with a strip 7 secured to the wall of the vehicle body, to enablethe section 4 to swing toward said wall when the door is opened, so asnot to form an obstruction. I

The section 4 extends close to. the roof of the vehicle body, and thesection 4 is under light spring pressure in the direction of the dooropening, so that when the section 1 is swung toward the door, thesection 4 will swing under the spring influence toward the wall of thebody. When the door is closed and the section 1 swung to operativeposition it will contact with the section 4 and swing it to operativeposition also. n

The sections 1 and 4 are concaved in horizontal cross-section, so as tohave a better effect in deflecting the current of air into the frontpart of the vehicle, as seen by the arrows in Fig. 3, thereby avoidingthe objectionable draft in rear of the opening. a

It is understood that the separation of the parts 1 and 4 is onlynecessary, if one part of the screen is fixed to the door. In the othercase, an undivided guard. going upto the roof of the coach issuflicient.

In order to avoid part of the current of air caught by the screenflowing downwardly against the feet of the passenger sitting near thewindow, the lower part of the screen is closed by a shutter or sheet 5of so metal or other material, the rim of which is suitably turnedupward. This sheet refle cts the downward flowing current of air andbreaks the force of the following."

The same ora similar shutter -may of course be arranged at .the upperend of the screen to prevent the upward flowing current ofrair fromflowing past the upper end the door so that it will not obstruct passeni1 the screen I The wind-screen as described above permits of enjoyingfresh air even in coaches, sedans and other closed vehicle bodies with:out being troubled by the current of air ,a tr'ue comfort in the hotseason.

Instead of-beingfixed to the guard 1 the shutter 5 breaking the currentof air directed downward may be fixed to the door or to the sidewall ofthe car, separately from guard 1 and the result will be the same.

Having thus described the invention, what is fclaimed as new is:

1. The combination with a' vehicle body having a side wall rovided witha door hav- 6 ing an opening, a wind-screen having a section hingedlyconnected to the door at the rear edge of the opening and within thebody, and having another'section hingedly connected with said wall andwithin the 1 body and spring influenced to swing toward 4 said opening,the firstnamed section being arranged to contact with the secondnamedsection for swingin% the latter away from said wall with" the rstnamedsection.

'2. The combination with a vehicle body having a side wall provided witha door having an opening, of a wind-screen having one section hingedlyconnected to said door at the rear edge of said opening and within thebody, and having another section hingedly connected to said wall andwithin the body, one of said sections being adapted to swing with theother toward and away from said wall.

Y 3. The combination with a vehiclebody having a door with an openingtherein, and a wind-screen comprising a lower section hingedly connectedto said door and rearwardly ofsaid opening, 'an upper'section hingedlyconnected to the vehicle body and overlapping said lower section andextending substantially to the roof of the Vehicle body, and a shutteradapted'to close in the lower end of the lower section.

4. The combination with a'vehicle body having a compartment with a doorprovided with an opening, of a windscreen attached to the door at therear edge of said opening and within said compartment, and means 40 forpreventing the current of, air which rushes in through said opening intosaid "windscreen from flowing past the ends of said windscreen.

5. The combination with a vehicle body having a side wall provided witha' door having an opening, of a windscreen having cooperable sectionsone carried by said door 'at the rear edge of said openingandwithin saidbody and the other section bein fastened to said side wall, thefirstname secfiion being adapted to be swung toward said oor.

In testimony whereof I aflix my si ature.
